Question

which term describes the amount of charge that passes a point in a circuit each second?
a. current
b. resistance
c. power
d. voltage

Explanation:

Current is defined as the rate of flow of electric charge. The formula for current \(I=\frac{Q}{t}\), where \(Q\) is the charge and \(t\) is the time. Resistance is the opposition to the flow of current (\(R = \frac{V}{I}\), from Ohm's law). Power is the rate of doing work or the rate of energy transfer (\(P=VI\)). Voltage is the potential difference that causes current to flow (\(V = IR\)).

Answer:

A. Current
